Abstract:

ZrW2O7(OH1-x,Clx)2·2H2O (x = 0.016, 0.025) is prepared by using the acid steam hydrothermal (ASH) method. The chlorine contents of the crystals are measured by means of potentiometric titration and ICP, respectively. The as-prepared powders are characterized by X-ray diffraction, and their structures are refined by using the Rietveld method contained in the GSAS program. The results indicate that the chloride ion occupies the hydroxyl group crystal site statistically.
